The MRCOOL® DIY® 5th Gen Multi-Zone 48,000 BTU Ductless Mini-Split Heat Pump System provides efficient year-round heating and cooling for two separate spaces with a 12,000 BTU and 18,000 BTU wall-mounted air handler configuration. With 21.8 SEER2 efficiency, DC inverter technology, and R-454B refrigerant, the system delivers flexible multi-room comfort with efficient operation.
Built around MRCOOL® DIY® technology, this system uses pre-charged Quick Connect® line sets to simplify installation by eliminating the traditional evacuation and refrigerant-charging process for qualifying installations. The 12K air handler is designed for spaces up to approximately 550 square feet, while the 18K air handler can cover up to approximately 800 square feet, allowing each zone to be controlled independently.
The system includes Wi-Fi and Smart HVAC app compatibility, Follow Me®, low ambient cooling, Gold Fin® condenser protection, quiet operation, washable filters, and compatibility with Amazon Alexa and Google Home. The 48,000 BTU condenser operates on 208/230V single-phase power and is backed by a 5-year parts warranty and 7-year compressor warranty, with extended limited lifetime coverage available through the MRCOOL® Care Program.
